Documents and notes decision
Coda
A capable engineer can build a useful single-tenant subset (docs+tables+AI+basic automations) in about a week, but matching Coda’s enterprise features, deep integrations, real-time collaboration, and polished templates is substantially more work and likely not worth reimplementing for most teams.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Coda alternatives, with the arithmetic →
What a replacement has to do
- Create and edit rich documents that include tables with formulas, invoke an AI assistant to generate or summarize content, and wire basic automations/integrations to external tools.
What it still won’t have
- Real-time multi-user operational transform / collaborative cursors
- Enterprise admin controls, SSO, audit logs and compliance tooling
- The full catalog of 600+ native integrations and Pack Studio
- Polished templates gallery and onboarding flows at Coda scale
- Scale, reliability, and performance optimizations of a mature SaaS
What remains hard

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-tenant Coda-like mini workspace using Next.js (React) frontend, Postgres, and a Node.js API. Implement: (1) persistent rich-text documents and tables stored in Postgres; (2) a React table view with basic row CRUD and column formulas evaluated server-side; (3) an AI assistant endpoint wired to OpenAI-compatible API for chat, summarize, and adding rows; (4) auth with email+password and per-doc access controls; (5) simple webhook connectors for inbound/outbound integrations; include error handling, unit and integration tests, and Docker Compose for local dev. Out of scope: real-time OT/CRDT collaboration, enterprise SSO, extensive integrations catalog, and multi-region scaling.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
